Hi Hidetoshi,

the machine is the same and it used to work on 5.0. When I say
"work" I mean I've been able to read from the camera without any

If it helps dmesg output is below.

The code for reading is based on your dv/dvrecv/dvsend that you gave
me some time ago (approx. March this year) when I was wondering
why DVTS doesn't work. This code used to work on 5.0 so that's
why I'm a bit confused why it stopped working.

Thanks a lot,
